This invention relates to a fastener, for retaining two partsinassociation with each other, one of the parts extending through oraround the other part.

In greater detail, the fastener comprehends a simplified fasteningdevice which may take the form of a single piece of material such assteel of a resilient quality which is bent to a formation in which itmay be employed for retaining a window frame in association with anopening in a wall, such as a window frame of the class employed in thefront of a cabinet for a television and/ or a radio receiving set.

Of various media which have been employed for attaching windows,including their frames, to the casing of cabinets at openings thereinthrough which a television picture or a dial is viewed, none has beenwithout defects for assembly line manufacture, especially when thewindow, is of a plastic material and is an integral part of the frame.For example, fasteners of one class are too expensive insofar as theirfirst cost is concerned. Otherfasteners cannot-be assembled quicklyenough. And still others are unsuitable for use with comparatively softplastic material of the window frames and their use is frequentlyfollowed by fracture or deformation of the plastic parts.

Because of the present invention, a fastener may now be provided whichobviates the foregoing disadvantages since the fastener is inexpensiveof manufacture, may be produced from inexpensive material and whichcalls for no special skill in its application.

Other advantages of the invention, aswell as the invention itself, willbecome apparent from the following description of embodiments thereof,which description is illustrated by the accompanying drawings and formsa part of this specification.

In the drawings:

Fig. 2 is a sectional view, corresponding to Fig. 1, showing thefastener in the process of being assembled with the frame;

its edge portions only, to provide a window portion 12 centrally of theframe, through which an object such as a television picture tube or dialof a radio receiving setwithin the cabinet may be viewed. A flangeportion l3, which extends over the external surface of the cabinet fromopening {3, limits di spla cenient of the frame tothe right (Fig. l),and displacement thereof transversely of the axis of said opening isprecluded by intimacy of association of a rim portion M with thatportion of the cabinet defining the opening 9. The rim l4 extends to anedge thereof l6, adjacent the rear extremity of opening 9, and

is formed with lugs I1, any number of which may parallel arms 23.

be present on the edge and which are preferably integral with the windowframe i l. Each of the lugs I1 is apertured by a slot [8 to provide aseat or pocket for a purpose later to be described. These seats may alsobe provided by recesses molded or cut in the lugs, or may be provided bymeans of other members, having seats thereon, molded in the lugs.

A novel clip or fastener I9 is adapted to cooperate with each of theseats for anchorage of the clipto the frame II, and concurrently, forSecuring theframe to the cabinet. For a clearer understandingv of theoperation of this device, reference should be made to Fig. '3 whereinthe fastener is shown as a single piece of substantially resilientwirebent to the conformation shown.

As will be noted, the fastenerincludes at least one hook or intermediateportion 2! which is between and offset from the ends of a pair of innerparallel arms 22 bent at the ends to continue laterally away from eachother to outer Each of the pair of arms 22 provide, with arms 23, a wingportion 24 adapted to engage the inner surface of the rim 5% while thehook portion 2! extends into the slots-l8. Desirably, of course, thearms 22 are only slightly closer to each other than the length of theslot l8, so that when in association with frame II,
